We are adding a bathroom in our basement, we are on a septic system, and our plummer has told us we have to use a sewage ejector tank. He brought over a Zoeller pump,and the digging should start on Monday. We have been told by friends, that it isn't necessary to dig up our concrete and that there are upflush systems, or the quick jon by Zoeller. We are confused. What is the best way to go, with the best long term quality results. Also what is Zoeller's reputation? Thanks for your input.
